Prince's supporters left in remand for a dressing down (9)
I believe the answer is:
reprimand
'a dressing down' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'prince's supporters left in remand' is the wordplay.
'prince' becomes 'pr'.
'supporters left' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'in' means one lot of letters goes inside another.
'pr'+'i'='pri'
'pri' going inside 'remand' is 'REPRIMAND'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for reprimand that I've seen before include "Formal censure" , "telling off" , "Severe telling-off" , "Severe reproof" , "Tick off - carpet" .)
